H 25 Getting Started

2

1 Introduction

The Phase One H 25 single shot camera back is designed for

advanced photography applications with a need for

productivity, flexibility and the absolute best in image

quality.

The Phase One H 25 is able to capture large objects and still

reproduce the finest details. The rectangular formatted 22

megapixel CCD allows the Phase One H 25 to generate

image files that can be offset printed as large posters. The

CCD is mounted in Landscape orientation and practically fits

the horizontal area of a Hassleblad camera.

The ability to use the same software as all the Phase One

single shot camera backs and connect to a computer simply

by hot plugging allows the Phase One H 25 to integrate

perfectly with the productive and flexible workflow

appreciated by thousands of studios around the world.

The Phase One H 25 is based on the highly recognized Phase

One technology. This manual ”H 25 - Getting Started” only

describes features and functionality unique to the Phase One

H 25.

For a detailed guide to the application software, please refer

to the Capture One User Guide for Mac and PC.

2 Special H 25Features

The Phase One H 25 can be mounted on a wide range ofcameras including Hasselblad 555 ELD, 553 ELX, 501 CM,503 CW as well as Mamiya RZ67 Pro II and 4” x 5” viewcameras via an optional Phase One adaptor.

ISO Settings

The default film speed of the H 25 camera back is ISO 50.However, this setting can be changed to ISO 100, 200 or400 in the Capture panel of the Capture One application.

It is recommended to capture images using a film curve.That is done by selecting the film curve in the Capturepanel of the Capture One software. Click the camera icon inthe icon bar and select: “Film Standard,”“Film outdoor” or”Film extra shadow.”

Power management

The CCD on the H 25 constantly needs to be cleared fromprevious data before an exposure. This requires somepower consumption. Situations can occur where this is notconvenient (i.e. in connection with Phase One portablesystems where the batteries will get drained too rapidly).On electronically controlled camera bodies the powerconsumption can be drastically reduced by setting the Lowpower or Ultra low power mode inside the Capture OneApplication (Please read the section specific for yourcamera body to learn if you are able to use these settings.).

Double exposure protection

It is not possible to accidentially double expose the imageby capturing one image quickly after another when theH 25 is used on a Hasselblad 555 ELD. The electroniccommunication with the Hasselblad body ensures that theH 25 is ready before allowing release of the next shot. Onother camera bodies not using the electronically interfacefrom the H 25, the user has to wait for the ready beepsignal before releasing the next shot.

IR filter on the CCD

The IR filter (Phase One TG1 Infrared cut-off filter) ispermanently mounted on top of the CCD.

The filter may not be removed for several reasons:

l The focusing of the H 25 camera back will be damaged.

l It is only possible to remount the filter without dust inbetween the filter and the CCD if you have access tospecial clean room facilities.

l The Phase One Product Warranty is terminated.

Large format photography

The Phase One H 25 can be used on most large format

cameras via the optional Phase One FlexAdaptor and supports

all mechanical shutters and the Horseman ISS electronic

shutter. To ensure optimal image quality, Phase One strongly

recommends shutters that can be fired twice within four

seconds. The first release of the shutter activates the CCD,

the second release takes the picture. If the time limit of four

seconds is exceeded, the camera gives a warning “beep”

followed by a “ready” signal. If for some reason it is not

possible to fire the shutter twice within the time limit, the

camera will send a time-out error message to the screen.

3 Preparing to take pictures

Mounting the viewfinder mask

The image area of the Hasselblad camera body is approximately 6 cmx 6 cm, wheras the image area of the H 25 is 48.9 x 36.7 mm.Therefore, it is necessary to use the H 25 viewfinder mask. Removethe protection tape from the mask and mount it beneath the originalfocusing screen.

6

The viewfinder mask ispositioned in thebracket that holds thefocusing screen. Pleaserefer to the Hasselbladcamera manualinstructions before thefocus screen isremoved.

After the Phase Oneviewfinder mask ispositioned in thebracket, place theHasselblad focusingscreen on top of themask and slide theviewfinder top backinto place.


7

Mounting the H 25 on a Hasselblad camera

The H 25 is fully integrated with the camera body and actsas a true part of the whole camera system.

It is important to ensure that the bottom part of the H 25camera back is pressed well into the locking mechanismbefore the upper locking mechanism is pressed together.

To avoid the H 25 accidentally being released from thecamera body, you can use the enclosed screwdriver to lockthe H 25 locking mechanism on the top of the camera back.

Camera body specifics

A sync cable is connected from the lens to the C-connectoron the camera back on all Hasselblad cameras.

The flash cable is then connectedto the F-connector on thecamera back.

When using the H 25 on a Hasselblad motorized body (i.e.

Hasselblad ELX series or Hasselblad ELM series), a motor

cable is supplied to enable capture from the computer.

The cable is connected between the M-connector on the

H 25 and the DIN connector on the Hasselblad.

The motor cable is not needed when using the H 25 on a

Hasselblad 555 ELD body.

Avoid using A or AS mode.

Please note that the Phase One H 25 should not be

mounted while the camera is set to mirror up (S or RS

modes). Also make sure that the lens is not jammed or

locked open on the “B” setting when connecting the flash

sync cable to the Phase One H 25.

Power Condition:

If you are using the Hasselblad 553 ELX you should set the

Camera power mode to ”Normal.”

4 Maintenance

Cleaning the IR filter

When the Phase One H 25 camera back is not attached to a

camera, the camera back must be protected with the

protection plate. However, over time dust may accumulate

on the IR filter. This will degrade the image quality if not

removed.

Please follow the directions included in the CCD cleaning

kit in the H 25 package.
